FIRST ON 12: Superintendent responds to porn in Petersburg classroom

A Petersburg Schools substitute teacher has been removed as officials investigate claims students were watching porn inside a classroom.

A video posted on Facebook showed several students watching a pornographic movie inside a classroom, as the substitute teacher sat behind his desk. A user sent NBC12 a link, claiming the video was from Petersburg High School.

School Superintendent Dr. Joseph Melvin said he had not seen the video until it was shown to him by NBC12.

"We immediately removed the substitute teacher," said Dr. Melvin. "All students who were involved have been disciplined."

The date on the white board in the video indicates it was taken Tuesday. The video has since been removed from Facebook.

"It is not something that we certainly would want in our schools or in any school," said Dr. Melvin."It's just a very, very, horrible situation."

The students were watching the video on a Dell desktop computer. School officials insist they have filtering devices that prevent students from watching inappropriate material at school.

Dr. Melvin would not comment on how the students have been disciplined.
